He explained everything as work progressed and informed me about aftercare,servicing etc.

I contacted Darren Grant on 07/02/2024. Spoke with someone, gave details of the work needed. The person then said they would speak with the manager about the job and call me back. She confirmed the number to call me back on, then never returned the call.

I had an issue with 4 of my radiators not getting hot. A powerflush did not resolve the issue. However Billy the engineer from Darran Grant Ltd identified the problems. This was not an easy job as it required gaining access to the pipes below the floorboards to try and locate where the blockages were. He resolved all the issues and was very respectful of the property and ensured everything was back to the way it was before he started. I would highly recommend their services.

I needed a new boiler due to my old system causing me a lot of issues so contacted Darran for a quote. From initial contact to completion of work I was really pleased. I was spoken to about the options I had and opted to switch my heating system to a combi boiler. Darran booked me in for a time that was suitable for me. When work started both Darran and Billy were very professional. Both really friendly as well. Work completed to a very high standard and I am really pleased with the completion of the work. I will not hesitate to have them back for boiler servicing etc.

Cannot speak highly enough about Darran Grant Ltd. We needed to replace our old combi boiler which was 14 years old with a new boiler and have cast iron stack/vent pipe removed and replaced with new plastic pipe. Also, 2 rads were replaced. When Darran came to view the job. We discussed what was required, also the performance of our heating system to the kitchen and bathroom After consultation, it was suggested that the pipes around the system to this area were too narrow (8mm) for the heating system. He needed to upgrade the pipes in this area with 15mm. I asked Darren to replace the radiators in the bathroom and kitchen. Before recommending a boiler to meet our needs Darran checked the cold water flow rate. We agreed on a start date and work commenced on the Tues16th of May A few days before the start day Emma contacted me and confirmed that Darran would be with us on the date agreed. Darran arrived on the date and time agreed with his employee Billy and didn’t waste any time getting started. Both Darran and Billy were very conscientious, nothing was too much trouble they were a delight to work with. The work was finished to our complete satisfaction with no mess at all and our heating system working perfectly. I Would highly recommend using Darran Grant Ltd Darran and Billy were excellent workers professional and friendly. I would like to say that the service provided by Emma in the office was also excellent, Truly professional service all round

We first contacted Darren Grant last October to discuss reasons for inadequate performance of our heating system, ( radiators not getting warmer than Luke warm). After consultation it was suggested that all the pipes around the system were too narrow (8mm) for the heating system. He needed to upgrade all the pipes throughout the house with 15mm. Also, as our boiler was probably approximately 10 years old it was suggested that it be replaced with a brand new Worcester Boiler. However, as Darren was so very busy he was very honest in telling us he wouldn’t be able to commence work for a number of months. We were prepared to wait. Work commenced on the 24th of April 2023 and was estimated to take about a week to complete. At 8am on that day, Darren arrived with his employee Billy and didn’t waste any time getting started. Bang on target, the work was completed on Friday 28th. The work was finished to our complete satisfaction with no mess at all and our heating system working perfectly. All our new carpets which had to be taken up in every room were relayed and you wouldn’t have known they’d been there in the first place. A wonderful job, two exceptionally nice people.

Darran Grant Ltd (accredited Worcester Bosch heating engineers) installed a new Worcester Bosch oil boiler to replace my old one. The whole process was a seamless exercise from when I received their quote to when the work was completed. I was very fortunate to find Darran Grant Ltd. - professional, efficient, polite, tidy, an eye for detail and time also whilst on site to explain matters to me. In a nutshell, a faultless exercise.

Darran and Billy were excellent! Truly professional service. They managed to effectively fix our heating system without ripping up all the floorboards or knocking holes in the walls (as other engineers had suggested would be required to determine the problem!). Thank you both so much for doing such a good job! It’s refreshing to have had such reliable, honest, efficient, neat workmen complete the job and finally have a heating system that works again.

We contacted Darran for a replacement boiler as a neighbour of ours recently used the company for similar work. From the moment Darran arrived we knew we were in safe, honest, capable professional hands. Appropriate advice was given when needed, he is clearly very passionate and knowledgable in this area. The whole service before the work began was excellent and when it came to installation day this was great too. The team did long days, worked hard, kept the house clean and tidy! Can’t recommend this team enough! Thanks

Great support and advice to ensure that I had the replacement boiler that would work best for my type of property. Not pushy, just honest advice.

I was looking to upgrade my 16year old combi boiler with the added complication of the solar hot water. I used Darran Grant Ltd, a truly professional team that delivered what they said they would, in the timescale agreed.

On completion of the boiler installation they left the work area clean, tidy and took all of the rubbish away with them.

Very neat heating system installation
Customer Service

I approached Darren Grant Ltd to install a replacement boiler and pressurised hot water system in my home. My old system relied on a pump to supply a good flow to the domestic hot water system in the house. Since there are two showers in the property, the pump was able to maintain the flow. The downside was the noise from the pump, especially when using DHW at night. Darren installed a Worcester Bosh Green Storage cylinder to replace the old tank in the airing cupboard. A Worcester Bosch 8000 gas boiler installed in the loft space provided the heart of the system. A new pipe supply from the water main throughout the property and a larger gas supply from the meter to the boiler made the installation a bit more challenging. The work was carried out over a 5 day period and was done with the minimum of disruption and any mess was kept to the minimum. The pipework is exceptionally neat and tidy. The new system is very quiet and the two showers feel like power showers. The house is warm and comfortable. All the work is covered by Worcester Bosch 12 year guarantee. I have no hesitation in recommending Darren Grant Ltd.

We (myself and my husband Mick), recently had our (prehistoric) central heating boiler system replaced by Darran Grant Ltd and we were very impressed. Darren and Billy did all the work and they were wonderful. They worked solidly every day until the work was completed. They always tidied up after them and were very careful with their covid precautions (we had initially been worried about having anyone in the house during this covid period), but we felt totally reassured by the way they carried out the work. The final result was excellent and we have a wonderful working boiler and heating and hot water again!

I must say from the first visit I had from Darran to assess the work required I knew I was making the right decision. I required my old back boiler and tank removed and updated to a new combo boiler. I had already obtained other quotes prior to Darran’s but after meeting Darran I knew which one I would choose. I was impressed with Darran’s utter professionalism and manner which goes a long way with me. Darran and his colleague Bill turned up at precisely the time stated on the first day and got on with the work in hand. Owing to the stone two foot thick walls of our terraced house they encountered many problems but took it all in their stride. The work was completed at the time quoted and our home was left clean and tidy and all displaced items removed. Needless to say the Bosch Worcester system is operating perfectly and we are more than pleased. Thank you Darran and Bill for carrying out the work to such a high standard and for being such good company as a bonus. Highly recommended 👍
